THEOLOGY

some change was bound to come. That it might be an inflowing of new life by a new al-Ash'ari was their prayer. It is more than dubious whether even the keenest mind of the time could have recognized what form the new life must take. They had not the perspective and could only feel a vague need. But from what has gone before it will be plain that Islam had again to assimilate to itself something from without or perish. Such had been its manner of progress up till now. New opinions had arisen; had become heresies; conflict had followed; part of the new thought had been absorbed into the orthodox church; part had been rejected; through it all the life of the church had gone on in fuller and richer measure, being always, in spite of everything, the main stream; the heresy itself had slowly dwindled out of sight. So it had been with Murji'ism; so with Mu'tazilism. With the orthodox, tradition (naql) still stood fast, but reason (aql) had taken a place beside it. Kalam, in spite of Hanbalite clamors, had become fairly a part of their system. What was to be the new element, and who was to be its champion?

CHAPTER IV

Al-Ghazzali, his life, times, and work; Sufiism formally accepted into Islam.

WITH the time came the man. He was al-Ghazzali, the greatest, certainly the most sympathetic figure in the history of Islam, and the only teacher of the after generations ever put by a Muslim on a level with the four great Imams. The equal of Augustine in philosophical and theological importance, by his side the Aristotelian philosophers of Islam, Ibn Rushd and all the rest, seem beggarly compilers and scholiasts. Only al-Farabi, and that in virtue of his mysticism, approaches him. In his own person he took up the life of his time on all its sides and with it all its problems. He lived through them all and drew his theology from his experience. Systems and classifications, words and arguments about words, he swept away; the facts of life as he had known them in his own soul he grasped. When his work was done the revelation of the mystic (kashf) was not only a full part but the basal part in the structure of Muslim theology. That basis, in spite, or rather on account of the work of the mutakallims had previously been lacking. Such a scepticism as their atomic system had practically amounted to, could disprove much but could prove little. If all the categories but substance and quality are mere subjectivities, existing in the
